Not sure if this helps or not but on a 2005 Toyota Sienna LE, the dash-light dimmer switch is actually the trip odometer reset switch. Turning the trip odometer reset switch left or right controls the dash-light levels. Had it not been for the factory manual, and Google, I would have never known this.
The "trip odometer" on the dashboard doubles as a dimmer. So, the solution to no lights inside the Toyota Sienna is to turn the trip odometer up to turn the lights back on.
The trip odometer switch on the odometer itself is the dimmer on Toyota Sienna. If you turn this switch all the way to the left your panel would become dark. Simply turn the switch to the right and all panel lights would come on. I had a similar problem and the manual bailed me out.
I've researched this on the Internet and apparently the trip odometer button also serves as the dimmer for the dashboard lights. If you turn it (anti)-clockwise, your dash lights should come on. Its mentioned obscurely in the manual.
You need to replace the dimmer switch in your gauge cluster. This was caused by a bad ground happens all the time.
On my 2000 Forester, the dashboard illumination dimmer control is on the turn signal stalk. --Ken
it is below the headlight/dimmer knob, on the back of the dashboard. it is a pain to get to, requiring you to pretty much tear the dashboard out to get behind it
Probably because the dimmer switch is turned off. Turn the dimmer switch up and see if the dashlights and radio illumination lamps come on.
1.check the fuses under the dash 2. check the bulbs. 3. Check the dimmer knob. If it is the bulb it is easy to change. takes a couple of minutes. check the post on how to change the dash lights on a Toyota echo.
Replace bulbs? Check dimmer rheostat for open circuit Check fuse for parking/tailights
The dimmer switch is on the dashboard just to the right hand side of the steering wheel
fuse,or dimmer swich!
The 1993 BMW 325 dimmer switch is located on the lower left-hand side of the dashboard. The dimmer switch is a dial switch.
